This past Thursday we were placed into groups and asked to read Carl Zimmer’s What About God. In his writing‚ he talked about evolution. Zimmer argued that understanding evolution is essential for field such as geology‚ biotechnology‚ and modern medicine. Zimmer provides a thought provoking example of how understanding evolution is essential to creating modern medicine. He writes‚ “A vaccine may work against one strain of a disease like AIDS‚ but fail against more common ones because they’re only

Eubacteria (also known as true bacteria) It includes blue-green algae (cyanobacteria) such as Nostoc‚ Anabaena‚ etc. Photosynthetic bacteria contain chlorophyll a. Chemosynthetic bacteria oxidise various inorganic compounds and use the released energy for their ATP production. They have rigid cell wall and flagellum

plants. It is the first step towards making food - not just for plants but ultimately every animal on the planet. During photosynthesis: * Light energy is absorbed by chlorophyll‚ a green substance found in chloroplasts in some plant cells and algae * Absorbed light energy is used to convert carbon dioxide (from the air) and water (from the soil) into a sugar called glucose * Oxygen is released as a by-product This equation summarises what happens in photosynthesis: Some glucose is

observe. Firstly‚ look at the transparency of the river water. Transparency is the measure of the depth of light that can penetrate into the water (What is water transparency?‚ n.d.). It depends on the amount of particle scattering in the water‚ such as algae and sediment. The lower the turbidity of the water (the higher the transparency)‚ the higher the aesthetic value of the river. High turbidity of water causes by particulate matter can reduce the aesthetic value of the river because it can impact on

BACTERIA. CLASSIFICATION Bacteria are extremely small and some can be just seen with the naked human eye. They are much smaller than eukaryotic cells but are still very complex despite their size. .the cell is surrounded by a cell membrane that enclosees the bacteria cell. They are single celled organisms. Bacteria are prokaryotic cells and therefore do not have a nucleus and do not have a lot of organelles like: mitochondria‚ chloroplasts‚ and other organelles that are usually found in eukaryotic

Giant Clam (Tridacna maxima) The giant clam is the largest bivalve in the world. Some species can reach 4 feet in length. Their bright colors are caused by tiny algae called zooxanthellae. These algae use sunlight to provide nutrients to the clam and receive other nutrients in return. This species if found in the southwest

The dead bodies are the remains of microscopic algae and animals that live in the waters farther up in the ocean‚ but sink down into the depths after they die. The poop consists of fecal pellets from small‚ shrimp-like animals such as copepods or krill. The snot is mostly debris from gelatinous animals

bristles on its legs as strainers. Because algae are the daphnia’s main food source‚ it is clearly and advantage for the daphnia to stay where the algae are most densely populated. This is done by sight‚ but not by spotting the algae at a distance and heading for it. If the daphnia stumbles across a group of algae‚ the light seen by the daphnia will be slightly red‚ as most of the blue light in sunlight is removed as it passes through the cloud of algae. The slight redness of the light will cause

Marine Biodiversity is one of the assets of the Philippines‚ and because of this‚ the country bear the title of the “Centre of Marine biodiversity”. But as timed passed by‚ little by little‚ this asset is being disturbed because of human deeds‚ and if the authorities didn’t do something‚ the once known asset may turn into a burden for us. This study will focus on the effectiveness of the laws being implemented by the government and to test whether the laws are being implemented strictly or not.
